Proton upgrades privacy-focused Lumo chatbot

TechCrunch reported that Proton released Lumo 2.0, an upgrade to its privacy-focused public AI chatbot. The update adds image recognition and generation, document-focused Projects with user-controlled persistent memory, faster responses, and a new thinking mode for more complex questions. Proton says Lumo uses zero-access encryption architecture, does not retain server-side session logs, and does not use customer data for AI training or third-party sharing.
